# Schematic

## Expected Circuit

```text
ESP32 GND  -> LCD GND
ESP32 3.3V or 5V -> LCD VCC, only after checking module requirements
ESP32 SDA GPIO -> LCD SDA
ESP32 SCL GPIO -> LCD SCL
```

## Important Check

Before connecting SDA/SCL to ESP32, verify I2C pull-up voltage. ESP32 GPIO must not receive 5V.

## Actual Circuit

TODO: указать VCC, SDA GPIO, SCL GPIO и I2C address.
